NEWSPAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,805, dated August 23,1887.

Application filed January 2'7, 1887. Serial No. 225,630. (No model.)

To alZ whom it may concern:

Be it known that I, AUsrIN T. BASCOM, a citizen of the United States of America, residing'at Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Newspaper-Folding Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to improvements in newspaper-folding machines; and it consists in certainnovel features of construction, which will first be described in connection with the accompanying drawings, and then clearly r pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective view of the machine, the gripper-opcrating lever and a portion of the frame being broken out. Fig. 2 is an elevation of one side of the machine, and Fig. 3 is an elevation of the opposite side. Fig. 4 is a rear elevation of the first'fold receiver, showing the manner of its adjustment. Fig. 4"" is a broken top view of one of the frames h, showing the adjusting- Fig. 5 is an inverted ates the first'fold blade. Fig. 6 is a perspective view of a portion of the gripper mechanism, partly broken out to show the friction de- 0 vice. Fig. 6 is aperspective view of aportion of the gripper mechanism. Fig. 7 is a perspective view of so much of the first and second fold-receivers as is necessary to illustrate the manner of adjusting the latter. Fig. Sis ade- 5 tail elevation illustrating the manner of adj usting the tape-rolls and paper-stops. Fig. 9 is a detail perspective view showing the delivery-disks arranged on the driving-shaft and in position to receive the folded paper from the delivery-tapes and place it against the racks. Fig. 10 is a plan View illustrating a modified construction of the delivery-disks.

Fig. 11 is a detail perspective of the mechanism that operates the fourth-fold blade.

In the accompanying drawings, A represents the framework of the machine, preferably of iron.

B represents the feed-board, hinged at b and provided with the usual side guides, b.

0 represents the top plate of the machine, made of iron and perforated throughout its entire surface, in order to prevent air from gathering under the paper as the latter is drawn toward the gage, and 0 indicates two strips of wood or other suitable material secured to 5 the top plate, over which the paper is drawn, one of said strips serving as a track for the caster supporting the outer end of the gripperframe, as shown in Fig. 1.

D is the paper-gage, adjustable on the top plate of the machine and having openings, as at d, for strips 0 to lie in, and to permit the passage of the grippers, the gripper-frame in its forward and backward movements passing over the top of the gage.

E is an upright bar, preferably of wroughtiron, bolted to the frame-work, for a purpose hereinafter stated, and E is a horizontal rod, secured at one end to bar E and at the other end to a right-angular extension,a,ofthe frame.

The gripper mechanism consists of a light wooden frame, 1, attached at one end to a concave metallic slide, 6, secured on rod E, so as to move freely thereon. The slide is provided about centrally with a tubular extension, 7 5 2, in which is placed loosely cork or other like frictional material, 3, and a set-screw, 4, with a metallic disk, 5, interposed between the end of the screw and the cork, to prevent the former from pressing into the latter. The slide so ehas a hooked projection, 6, at one end, and a short distance in rear of said projection it is provided with a short standard, 7, capable of beinginclined from a vertical position, the top of this standard being bent outward at a right angle. The grippers 8 are constructed 7 preferably ofspring-steel, their upper jaws being secured to the upper side of frame 1. The outer lower jaw is hinged to the lower side'of said frame, and the other lower jaw is hinged to a rod, 9, attached to frame 1 in such manner as to rock freely. The outer end of this rod is bent forward at a right angle and engages midway between the grippers with another rod, 10, connecting the lower jaws, as 5 seen in Figs. 1 and 6,whereby the movement of said jaws is equalized-that is to say, the jaws are caused to open and close simultaneously and grip the paper with equal firmness.

- The inner end of rod 9 is bent upward and formed into an elongated loop, 11, at its top, the forward rock of rod 9 and consequent strain on the grippers being limited by the hooked projection on the slide, as will be apparent. The outer end of the gripper-frame is supported by a caster, 12.

F represents a lever for giving motion to the gripper mechanism. The lower end of this lever is pivoted on a bolt, 13, adjustable in a slot, 14, in the lower side rail of the machine-frame, and its upper end passes through the loop 11 on rod 9 of the gripper mechanism. Motion is imparted to this lever by means of a connecting-rod, G, one end of which is journaled on awrist-pin, 15, secured to a sprocket-wheel, 16, on the main shaft, the other end being secured by a bolt, 17, adjustable in a slot, 18, inlever F. By this construction the gripper mechanism can be given sufficient travel for the largest-sized newspaper, and its rearward movement can also be limited for paper of a smaller size, thus avoiding any unnecessary travel, for it will be observed that if I wish to shorten the rearward movement of the gripper mechanism I can do so by simply raising the bolt 17 in slot 18 of lever F; but this adjustment alone would also shorten its forward movement. This difficulty is overcome, however, byv the adjustability of the lower end oflever F.

The upper end of lever F passes through loop. 11 on rod 9, and as the lever is moved rearward or fromthe feed-board it bears against the rear end of the loop, rocking rod 9, closing the grippers, and moving the gripper mechanism. The lever thus acts directly on the loop until the former has assumed an angle sufficient to come into cont-act with standard 7, when the pressure will be gradually moves on rod E.

transferred from the loop to the standard. When the loop has been thus released from pressure, the bite of the grippers on the paper will be so slight that when the leading edge of the sheet strikes against the gage D the grippers will be drawn from the sheet. In Figs. 2 and 3 the gripper mechanism is shown in its extreme rearward position. Now, on further rotation of the main shaft the upper end of lever F will be moved in the opposite direction and bear against the forward end of loop '11, which will rock rod 9 forward and open the sheet, by which time leverF willhavebeen started to the rear, thus closing the grippers, and so on. The standard may be given anyv desired inclination, so as to engage with the lever sooner or later, as will be apparent. In the for-ward movement of the gripper mechanism the power of the lever will be exerted on the front end of the loop 3 but the forward rock of rod 9 will be limited by the engagement of'its upwardly-bent portion with the hooked projection 6 on slide e. The grip or bite of the grippers is governed by the power necessarilyexerted on the loop to move the gripper mechanism, and this power in turn is governed by the freedom with which the slide If a firm-grip is necessary,

as when working heavy paper, set-screw 4 is turned so as to press the cork or other frictional material against rod E, and vice versa.

H represents the first-fold receiver (in which the first fold of the paper is made) located transversely of the machine. It consists of two sets of light slat-frames, h h, the frames h at the center abutting against and lying flush with two inturned rounded iron posts, 19. (see Fig. 7,) rising from a slotted plate, A, extending longitudinally of the machine'frame at the bottom and forming part of the same, the said frames being secured in place at the top by screws passing through the top plate, and at the bottom by dowel-pins entering lugs on plate A, and also on the siderails of the machine-frame. The other frames, h, of this receiver are set facing the frames h, and are made adjustable closer to or farther from them, in order to narrow or widen the passage-way for the paper, in the following manner: To plate A, on either side of its slot, the frames h are attached at bottom by means of pivot-hinges 20, tightened by nuts 21, Fig. 4, and at top they are hinged in like manner to any suitable projection on the machine-frame or to a kerfed piece, A, (best seen in Fig. 3,) designed to steady the top of the second-fold blade until it reaches the second-fold receiver. By this construction the inner ends of the frames It can be adjusted as desired by simply loosening the nuts on the hinges, setting the frames,and then tightening the nuts. The outer ends of these frames are made adjustable by means of earns 22, engaging with a downwardlyextending cross-plate, A, of the machine frame. Not only are the frames It thus made adjustable with relation to frames It, but they are also capable of being swung open on their hinges, so that if a sheet should become lodged in the receiver it can be readily removed. The frames h It are held together at their outer ends by anysuitable device, as by a hook, Fig. 2, of proper length, or a turn-button, Fig. 4, of proper thickness. The opposing faces of the slats composing these frames are lined with felt or other suitable material to afford a frictional surface for the paper, so as to prevent it from becoming displaced as the fold-blade is withdrawn.

I represents the second-fold receiver extend ing longitudinally of the machine and constructed of slat-frames t i, substantially like those before described. These frames are made adjustable toward and from each other, in order to regulate the width of the passage-way and to keep it central with relation to the opening from the firstfold receiver, as follows:

ceases I a bolt heads being countersunk therein, (not shown,) and also through the upright 23, and are provided with thumb-nuts 26 on their screw-threaded ends. This description applies to the upper one of the frames, 11, but it applies equally well to all the other frames of the second-fold receiver, with the single exception that (there being no necessity for hinging them) they have but one upright, which, however, equals in width the combined widths of the two beforementioned. Now, in order to effect the adjustment, all that is necessary is to first turn the wood-screws until the up right is carried forward or backward the proper distance and then tighten thumb-nuts 26 on bolts 25.

J represents the third-fold rolls journalcd in the machine-frame parallel with the second fold receiver, their journals passing through the frame at the front of the machine. and bearing miter spur wheels 27, which gear with a bevel-wheel, 28, the shaft of which" (supported in a bracket, 29,) bears a small sprocket-wheel, 30, over which passes a drive-chain, 31, which passes round and is driven by a large sprocket-wheel, K, secured on the driving-shaft L, the tension of the chain being governed by a sprocket-tension, 32. Wheel K (for a purpose which will hereinafter appear) is provided on one side with a broad rim, is, Fig. 1l,extcndingpart way round the wheel, one end of said rim being turned inward at a right angle, as at It, and on the outer side of the rim is alug, k about half the width of the rim.

M represents the fourth-fold rolls, journaled in the lnachine frame at right angles to the third-fold rolls, and below the line of contact of said rolls. The fourth-fold rolls are driven by means of a drive-chain, 33, passing around a sprocket on the rear roll, under a sprocket on the front roll, and around sprocket-wheel 16, the chain being supported in contact with the sprocket on the front roll by means of a small sprocket, 34, journaled on the side of the machine-frame.

The folding-rolls are adjustable toward or away from each other by means of movable journal-bearings, as 35, secured by bolts passing through slots in the machine-frame, as illustrated in Fig. 3. All of the rolls are covered with felt or other suitable fabric.

Carrier-tapes 36 pass around the lower one of the third-fold rolls, and extend parallel with and in a plane slightly above the fourthfold rolls to small pulleys 37, free to revolve on spindles adj ustably mounted in slotted brackets 38, swung on bolts 39, Fig. 8, entering thejournal-bearings 35, and provided with nuts 40 for tightening the brackets against the bearings. Thus the brackets may be swung forward or backward to loosen or tighten the tapes, as desired.

Stops 41., designed to arrest the paper as it is carried forward on the tapes, are swung on bolts 42 in brackets 38 in the same manner as those brackets are swung to the journal-bearings 35, and are therefore adjustable in like manner.

Other tapes,48,leading to the delivery mechanism, pass around the rear one of the fourthfold rolls, under the front roll, and over pulleys 44, mounted in brackets 45, adj ustably bolted (not shown) to the lower rail of the machine.

N represents the fly for throwing the paper from tapes 43 against a rack, 0, adapted to slide on a frame, P. The fly is hung to the driving-shaft of the machine by means of metallic straps46, which loosely encircle said shaft in aslightly spiral direction, as seen in Fig. 1, and each of these straps bears against a stud (not seen) projecting from that side of the head-block of rack-frame P next the shaft, these studs being so situated on the headblock that the inner edges of the straps 46 will bear against them. The fly is provided near its bottom with a projecting lug, 47, with which a tappet, 48, secured to the drivingshaft, engages for throwing the fly forward. Owing to the spiral fly-straps 46 hearing against the above-mentioned fixed studs, the' fly, as it is carried forward by tappet 48, is also moved longitudinally on the drivingshaft, so that lug 47 will be freed from the tappet at the proper time, allowing the fly to fall back to the tapes, it being retracted by any suitable device, as a weight or a spring. The head-block of rack-frame P has metallic bearings 49, which overlie the driving-shaft, being slightly raised above the fly-straps in order to prevent the paper from coming into contact with the latter.

The practice of working dry calendcred paper is now somewhat in vogue with printers,

and this has led me to devisea novel delivery admirablyadapted to meet the requirements in this case. \Vhen the paper is put through the folding-machine in a dampened condition, the fly will lay it firmly against the rack,where it will remain until the succeeding sheet is laid against it; but I have found that this is not always the case with dry paper, for some. times the folds of the paper will open and drop back onto the fly as it moves toward the tapes, thus allowing the next paper to enter between its folds. With the delivery mechanism that I am now about to describe this cannot happen, for the folded paper as it emerges from the machine is held positively against the rack until another paper is ready to be placed against it. This mechanism is constructed as follows:

Q represents a series of metal or wooden disks, usually three, each provided with a hub and formed with back wardly-extending fingers 50 and an elongated opening, 50, extending from the periphery to the hub, but in front of it, the rear Wall of this opening being rounded at the top in order to allow the paper to pass freely into the opening, all as clearly seen in Fig. 9. The disks are rigidly secured to the driving-shaft of the machine, which is 10- eated about midway between the tapes and the rack-frame, (it being understood that the fly is to be 'removedJand timed so that their frame.

tance between the disks.

openings will be directly before the end of the tapes 43 just as the folded paper is ready to pass therefrom. The ends of the slats forming the rack-frame P extend forward some dis- Now, in the operation of the machine the folded paper will be directed by tapes 43 into the openings in the disks, and as the disks revolve it will be carried around until it is brought to rest by its lower edge striking on the slats of the rack- Then as the disks continue to revolve their openings will gradually recede from the paper until the latter is entirely free from them, when it will fall against the rack. As soon as this occurs the peripheries of the disks will come into contact with and bear against the paper, th'us holding it firmly to the rack until another paper has been delivered, and so on, as will be apparent from the drawings. The devices herein termed disks may also be -formed of wire, bent so as to leave the elongated opening, as shown in Fig. 10.

It may be desirable sometimes to throw the paper off at the third fold, and for this purpose I employ a lever, R, pivoted to the machine-frame, and provided with a'curved toepiece, 51,with which tappet 48 on the driving shaft engages to rock the lever. To the inner end of this lever is attached a wire throw-off, R, bent at a right angle, so as to lie parallel with and behind the fourth-fold rolls. In using this throw-off it is only necessary to remove the fourth-fold blade, when, in the upward movement of the lever, the th row-off will lift the paper from the tapes and cant it over onto a rod, r, in front of and slightly below the tapes, and from'this rod the paper will fall onto or into the delivery mechanism.

S represents the firstfold blade, secured at one end to a sleeve, 8, adapted to slide freely on bar E, the free end ofthe blade being steadied above the receiver by means of a standard, E", to one edge of which is bolted a thin strip, 6 of wood or other suitable material, washers e being interposed between the strip and standard, as seen in Fig. 3. Movement is imparted to this blade by means of a lever, S, one end of which is pivoted to an extension, 01, of the main frame, and to the other end of the lever is pivoted one end of a link, S the other end of the latter being pivoted to the sleeve 3. Lever S is operated from the driving-shaft by means of wrist-pin 15, crank 52, and connecting-rod 53, the upper end of said rod being journaled on a wrist-pin, 54, which screws thropgh one side of a movable block, 55, on the lever and bears against the latter. By this construction the travel of the folding-blade can be adjusted accurately to fold papers of different sizes. To make this adjustment I first turn the drivingshaft until the lower end of the connectingrod 53 is in its'low'est position, and then move the block 55 on the lever toward or away from the pivotal point of the same, according as it is desired to give the fold-blade a' longer or shorter travel, and then tighten wrist-pin 54.

T represents the second-fold blade, attached at its bottom to a right-angularly-bent strip of metal, 56, Fig. 4. This strip is bolted to the bottom and at one end of a short sliding plate, 57, Figs. 4 and 5, the sides of which, at each end, are turned upwardly to form sleeves 58, which loosely clasp a bar, 59, bolted to the under side of slotted plate A, washers being interposed between said plate and the bar, as seen in Fig. 4. This folding-blade is operated by means of a link, 61, pivoted at one end to sliding plate 57, the other end of the link being pivoted to a lever, 62, to which is riveted a shoe, T, pivoted on a wrist-pin, 63, secured to the flange a on the side rail of the machineframe, the shoe being recessed, as at t, Fig.5, forming a heel, t, and a toe, t, the latter being extended as shown. In the operation of the machine the shoe engages with a frictionroll, 64, Fig. 2, carried by abolt, 65, screwed into the under side'of a sliding bar, 66, free to move in ways 67, bolted to flange or of the frame, as seen in Fig. 2, the under side of said bar being slightly concave to reduce friction. The sliding bar 66 is reciprocated by means of a connectingrod, 68, journaled at one end in bearings 69, cast on the bar, and journaled at the other-end ona wrist-pin. 70, adjustable'in a slotted crank, 71, secured to the main shaft, the inner end of the hub of the crank being formed as a clutch to engage with a like clutch (neither of which is shown) formed on the hub of the drive-wheel 72, loosely mounted on the main shaft, but adapted to be thrown into clutch engagement with the crank by a lever, 73. A coiled spring, 74, is attached at one end to bar 66, and at the other end to the machine frame. and steady the movements of the machine, it being so arranged as to exert its power while the first fold blade is ascending.

U represents the third-fold blade rigidly secured to one end of a rock-shaft, 75, mounted in short standards 76,'rising'from-the main frame, as seen in dotted lines in Fig. 2. The other end of the rock-shaft, bent at a right angle, passes through one end of a short slotted lever, 77, pivoted to a standard secured to the bottom rail of the frame, which lever is operated by a tappet, u, rigidly secured to the drivingshaft, this tappet being provided with a laterally-projecting lug, 78.

V represents the fourth-fold blade, secured to a shaft, 79, mounted in the frame of the machine. To oneend of this shaft is secured an arm, V, formed with a hook at its lower end (see Fig. 11) and provided with a projection, 1;, on its inner side, just above the hook, and another shorter projection, e, at the extreme end of the hook, the said arm engaging with the rim on wheel K.

The operation of the machine is as follows: The moving parts of the machine being in the position illustrated in Fig. l, and power ap* plied to the driving-shaft, the first-fold blade This spring serves to equalize -IIO will continue to rise until crank 52 is brought into a vertical position, during which time the grippers will move forward to the sheet which has been fed down by the operator. Then, when the crank moves over the center the folding-blade will begin to descend and the grippers will commence their rearward movement, thus rocking rod 9 and closing the grippers on the paper, which is drawn back until its edge is brought against gage D, (which should be set so that the middle of the sheet will lie directly over the first-fold receiver,) when the grippers will open and release the sheet. Just as the paper is brought to this position the first-fold blade strikes it and carries it down into the receiver until the center of the once-folded sheet is opposite the line of contact of the third-fold rolls, when the folding-blade will at once begin to ascend. At the instant it rises out of the receiver, (the grippers having meanwhile advanced to take another sheet,) the friction-roll 64, carried by slidingbar 66, comes into contact with the heel of the shoe T and enters the recess, thereby moving the lever 62, so as to drive the secondfold blade into its receiver, the thus twicefolded sheet being carried forward until its center is opposite the line of contact of the fourth-fold rolls. WVhen the second-fold blade reaches the limit of its forward throw, the sliding bar 66 will commence moving in the opposite direction, which movement will carry the folding-blade out of the receiver, the blade coming to rest as soon as the wrist-pin 64 leaves the recess in the shoe. The blade being-carried back very quickly, its momentum would sometimes throw the point of the heel of the shoe directly'in the path of the wrist-pin; but this difficulty is avoided by a spring-wire, 80, secured to the slotted plate A of the frame, which causes the folding'blade to rebound slightly, which swings the top of the shoe into position to be acted on by the wrist-pin, so that by the time the latter is ready to enter the recess in the shoe the heel will be in proper position.

It may be here remarked that the shoe is an important feature in the propulsion of the second-fold blade, as by means of it the blade is allowed to stand at rest out of the receiver during half the revolution of the driving-shaft, whereby the sweep of the bladepropelling lever is considerably shortened as compared with the sweep necessary when a rack and pinion are used.

As soon as the second-fold blade has cleared the receiver, tappet u on the driving-shaft strikes the end of rock-arm 7 5 and carries it upward, lever 77 swinging with it, thus driving the third-fold blade and the twiee'folded sheet between the third-fold rolls, and then when the tappet passes from under the rockarm the lug 78 will engage with the under side of lever 76 and force the end of the rock-arm down, thereby withdrawing the blade. As

the paper emerges from the third-fold rolls, it is carried by tapes 36 over the fourth-fold rolls until arrested by stops 41, when lug k on the rim of wheel K comes in contact with projection 0 on arm V, thus swinging said arm outwardly, and thereby giving the fold-blade a downward movement between the'rolls. At the moment lug 7c leaves projection v the inwardly-turned portion 7a of the rim engages projection 1) on the hook portion of the arm and swings the arm inward, thus raising the blade, the projection 12 meanwhile reaching the curved portion of the rim and holding the blade elevated until the rim has left it, the lug It, not lying in the path of said projection, freely passing it. When the sheet has received its fourth fold, it is carried by tapes 43 to the delivery mechanism.
